I was lucky enough to get an invite to http://www.playce.com/. I have several invites to give you to anyone who might be interested.
plaYce is “Making the World a Playground” by providing a 3D virtual world for games and social interaction, based on the real world.
plaYce reconstructs the world in 3D and streams it with high frame rate from within your browser. It does not need any large download to play the latest visually appealing games.
Currently there is only one game available called Downtown Defender, which has some similarities to tower defense map in Warcraft III. Soon new games will arrive ranging from car races in Hong Kong,to first-person shooters in the Amazon and treasure hunts in Manhattan.
A word of caution: you will need pretty recent hardware for your computer to play. And you need gaming hardware otherwise performance will be slow. So far I have really enjoyed Downtown Defender and look forward to the other games that will soon be emerging at plaYce. If you want an invite just leave a comment below. I only have a few so first come first served.
